**I was invited to a party.
Suddenly I farted when an angry man shouted: “Why do you fart in presence of my wife?”
I only gazed him for some moments and calmly told him:”Sorry I didn’t know it was her turn.”**

Similar, where the patient complains about their constant farts, and actually apologises for dropping one in the office; whereupon the doctor goes and fetches a six-foot-long stick with a brass hook on the end, and the patient says “Dear God, you’re not going to put that up my ass are you?” and the doctor says “No, I need to open the top window, the fucking stink in here is terrible!”
